Patented July 11, 1933 I OTTO H. IBA'UHANN, OF BCKITTRIGK, MISSOURI ran comnoi. 'eovnanon Application am July so,

This invention relates to a governor, mainly designed for use on tractors, the general object of the invention being toprovide means operated by the air from the cooling fan of the motor of a tractor for controlling the throttle of the motor.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, ref

erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a fra entary elevation of a motor and its fan s owing the invention in use.

Figure Figure 2 is a top plan view of Figure 1. 3 is a front view with the fan omitted. Figure 4 is a detail view showing how the rotary shaft of the device is attached to the throttle plate or valve member. Figure 5 is a detail perspective view showing the fiat bar attached to the front end of Figure 6 is a view of the bent rod for permitting movementof the blade member of the rotary shaft.

Figure 7 is aview of rotary shaft.

In these drawings the letter M indicates the motor, the letter F the fan and the letter I indicates a portion of the inlet manifold of the motor into which the explosive mixture is introduced by the tubular part T, the flow bein controlled by the throttle plate or valve mem r P.

In carrying out my invention I provide a shaft 1 which has a notch 2 at one end thereof 5 engaging the tongue on the spindle of the throttle plate, as shown in Figure 4, this shaft passing through a plate 3 which is fastened to t e governor attaching flange 4. This shaft 1 is rotatably supported m a bracket 5 which is attached to the top of the the rear part of said 1932. Serial No. 627,044.

motor by one of the bolts 6 which fastens the front part 8 which is twisted as shown in Figure 1. Y

A flat lever forming bar 9 is pivoted intermediate its ends to the lower part of the portion 8 as shown at 10 and the lower part of this bar 9 is twisted as shown and its extremity fastened to the blade forming member 11, such blade forming member being provided with a slot 12 at the upper end thereof.

A rod 13 has one end'bent at right angles as shown at 14 with its extremity threaded so that it can be placed in a threaded hole in the upperend of the lever 9 and the other end is bent twice at'right angles asshown at 15 with its extremity passing through a hole 16 in a flat plate 17 which has a threaded hole in its other end into which the front 'end' of the shaft 1 is threaded.

the rod 13 and its rear end is connected to a hand lever 20. pivoted at its lower end to abracket 9-1 by a bolt 22 which has a spring 23 thereon so that the lever 20 is frictionally held in adjusted position on the bracket.

From the foregoing it will be seen that the blade member 11 1s located'in rear of the A wire or rod 18 has a loop 19 formed at its front end which fits over the part 14 of throttle controlling means the member 11 moves rearwardly thus moving the upper end of the lever 9 forwardl which causes a movement of the rod 13 WhlCh will result inthe bar 17 giving the shaft 1 a partial rotary movement so as to partially close the throttle plate P and thus the speed of the motor will be checked.

Thus I have provided simple means actuated b the air fan of the motor so that.

the spec of the engine is automatically controlled and the engine is prevented from racing. If the operator wishes to regulate the speed.-

of the engine by hand he can do so by adjusting the lever 20 for the rod 18 by moving bination and arrangement of the several parts provided that such changes fall within the scape of the appended claims.

aving thus described my invention, what I claim as new is:

1. A governor for an internal combustion motorincluding a fan and a throttle memher, a lever pivotally supported in rear of the fan, a blade carried by the lever and acted on by the air from the fan, a member connected with the throttle valve and means for actuating the member by the movement of the blade, a hand lever and means for connectin the hand lever with the first mentioned ever.

2. A governor for an internal combustion motor including a fan and a throttle member, a lever pivotally supported in rear of the fan, a blade forming member, attached to the lower end of the lever and acted upon by the air from the fan, a shaft rotatably supported from a part of the engine andconnected with the throttle member, a plate having one end attached to the front end of the shaft, a rod having its front end bent at right angles connected with the upper end of the lever and the rear part of the rod being bent twice at right angles with its extremity passing through a hole in the plate whereby the partial rotary movement is imparted to the shaft by the tilting of the lever. v 3. A governor for an internal combustion motor including a fan and a throttle member, a lever pivotally supported in rear of the fan, a blade forming member attached to the lower end of the lever and acted upon by the air from the fan, a shaft rotatably supported from a part of the engine and connected with the throttle member, a plate having one end attached to the front end of the shaft, a rod having at its front end bent at right angles connected with the upper end of the lever and the rear art of the rod being bent twice at right ang es with its extremity passing through a hole in the plate whereby the partial rotary movement is imparted to the shaft by the tilting of the lever, a hand lever, a link having one end connected with the hand lever and a loop at its other end engaging the right angular part of the rod. 7

In testimony whereof I affix my signature.
